Filed Jan. 17, 1061, Ser. No. 83,292 3 Ciaims. c1. 4 s7 insure the true seating of the ball valve carried at the lower end of the valve rod.

Another important object of the invention is to provide a valve rod guide which may be readily and easily installed by persons unfamiliar with mechanics and without the necessity of making alterations in the conventional flush tank structure, to mount the same.

Other and further objects and advantages of this invention will be hereinafter described and the novel features thereof defined in the appended claims.

In the drawing:

FIGURE 1 is an elevational view of the flush tank valve and valve rod, constructed in accordance with the invention.

FIGURE 2 is a sectional view taken on line 2-2 of FIGURE 1.

FIGURE 3 is a sectional view taken on line 3-3 of FIGURE 1.

Referring to the drawing in detail, the reference character 5 indicates a valve seat formed at one end of the base 6 which provides an outlet for the overflow pipe 7 which is shown as supported by the base 6.

The device forming the subject matter of the present invention, embodies a vertical cylindrical member 8 formed with an axially disposed bore 9 extending throughout the length thereof, as better shown by FIGURE 1 of the drawing.

Formed in the wall of the cylindrical member 8, and arranged at a ninety degree angle with respect to each other, are slots 10, which slots are in direct communication with the bore 9 and extend from the upper end of the cylindrical member 6, and terminate in spaced relation with the lower end of the cylindrical member.

The lower end of the cylindrical member 8 is reduced and fits within an opening formed in the bracket 11, supporting the vertical cylindrical member in an upright position, the other end of the bracket 11 being clamped around the overflow pipe 7, as at 12, thereby supporting the bracket in various positions of adjustment as necessary for the operation of the guide.

The reference character 13 indicates the valve rod which is threaded in the ball valve 14, at one of its ends, the other end of said valve rod being bent upon itself providing laterally extended arms 15, 16, 17, and 18, the arms being also arranged at a ninety degree angle with respect to each other, as shown by FIGURE 2 of the drawing, to the end that the laterally extended arms fit within the slots 10, as shown by FIGURE 2 have free vertical sliding movement within the slots.

The arm 18 is appreciably longer than the remaining arms of the rod, and the extended end of the arm 18 is engaged by the flush tank valve operating the lever 19, so that as the operating lever 19 is operated to contact the arm 18, the rod and valve connected thereto will be elevated from the seat, allowing the water to pass through the outlet opening or valve seat, to the toilet bowl with which the valve forms a part.

It might be here stated that the upper end of the cylindrical member 8 is externally threaded, to receive the cap nut 20 which acts as a stop to prevent the accidental displacement of the upper end of the valve rod 13, and at the same time regulate the movements of the rod 13 in operating the valve.

As better shown by FIGURE 3 of the drawing, the lower reduced end of the cylindrical member 8, is externally threaded to fit within the threaded opening of the bracket 11, the bracket 11 being supplied with a securing screw 21 which passes through a threaded opening in the bracket 11 contacting with the threaded end 22 of the cylindrical member 8 securely locking the lower end of the cylindrical guide member 8 in its position on the bracket 11.

From the foregoing it will be seen that due to the construction shown and described, I have provided a valve rod guide embodying a cylindrical member formed with an axially disposed opening through which the valve rod of a flush tank operates, the cylindrical member being also provided with slots extending longitudinally thereof and terminating or spaced from the lower end of the tubular member, in which slots arms forming a part of the valve control rod, operates, the rod extending in horirelation with respect to the valve seat, so that rotation of the valve on the lower end of the valve rod is prevented, and the rod is accurately held for vertical sliding movement to the end that the valve of the flush tank will seat properly at each operation and will not hang on the valve seat to allow a continuous leakage of water under the valve.

Having thus described the invention, what is claimed is:

1. In combination with the valve seat, overflow pipe, and valve of a flush tank, a valve rod and rod guide, said rod guide comprising a tubular member having wall portions defining first and second pairs of diametrically opposed longitudinally extending slots, a portion of said valve rod positioned in said tubular member and having arms extending therefrom through said first and second pairs of slots, means closing the upper end of said tubular member, and bracket means to secure said tubular member to the overflow pipe.

2. In combination with the valve seat, overflow pipe, and valve of a flush tank, a valve rod and rod guide, said rod guide comprising a tubular member being vertically disposed and having upper and lower end portions, wall portions of said tubular member defining a first pair of diametrically opposed longitudinally extending slots, other 'wall portions of said tubular member defining a second pair of diametrically opposed longitudinally extending slots in a plane at right angles to said first pair, a portion of said valve rod positioned in said tubular member and having laterally extending arms substantially perpendicular to the longitudinal axis of said valve rod and extending through said first and second pair of slots to prevent rotative movement of said valve rod, a cap closing the upper end of said tubular member, the lower end of said tubular member removably secured in a bracket, and said bracket removably secured to the overflow pipe.

3. In combination with the operating lever, valve seat, overflow pipe, and valve of a flush tank, a valve rod and rod guide, said rod guide comprising a vertically disposed tubular member having upper and lower end portions, said tubular member having wall portions defining first and second pairs of diametrically opposed longitudinally extending slots in planes at right angles to each other, a portion of said valve rod positioned in said tubular member and having laterally extending arms substantially perpendicular to the longitudinal axis of said valve rod and extending through said first and second pair of slots to prevent rotative movement of said valve rod, one

4 of said arms having a length greater than the others and engageable by the operating lever for actuation of the valve, a cap closing the upper end of said tubular memher, the lower end of said tubular member removably secured in a bracket, and said bracket removably secured to the overflow pipe,
